About our remedial sealant in Great Thorness
A joint that keeps failing usually has a reason. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. Finding that cause comes before any new sealant. Typical jobs include torn expansion joints and kitchen joints letting water behind the worktop, across expansion joints, mouldy bath & shower sealant and leaking tray & enclosure joints.
Somewhere as small as Great Thorness, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
All our work comes with our one-year guarantee.

Your questions about remedial sealant in Great Thorness
What guarantee comes with remedial sealant in Great Thorness?
All our work, in Great Thorness and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can you do remedial sealant in Great Thorness?
Yes. Our work covers London and the South East, and Great Thorness is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Are you insured?
Yes, we are fully insured.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or send us an email.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
What if the leak is not the sealant?
In that case, we tell you what we’ve found. A plumber or fitter may be needed before any new sealant goes on.
Someone sealed over the old bead. Can you fix it?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Leave it or put it right?
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a small place like Great Thorness, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What we do, step by step
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours, depending on how many layers have to come out. Somewhere as small as Great Thorness, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

Landlords, agents and businesses in Great Thorness
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Common problems we fix in Great Thorness
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
It’s worth asking for a quote if you see:
- Movement joints that have split or pulled away
- Repeat leaks from the same joint
- Over-sealed joints coming away
- Caulk or the wrong sealant used in a wet area
Around Great Thorness, as everywhere, remedial sealant is only as good as the preparation behind it.

Remedial sealant around Great Thorness
Great Thorness is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For jobs in and around Great Thorness, choosing the right material for each joint is as important as a tidy finish.

What the job involves on each surface
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before we reseal.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Always have old sealant cut out, not covered
- Check ceilings under showers for marks
- Get the cause of a repeat leak found before resealing
- Air the bathroom so the sealant can dry
Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just call 0345 464 0079 or email us.
Don’t keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.
